grainient

grainient is a skill for Claude Code, Codex from nexu-io/motion-anything. It costs 43 tokens per session (167 once invoked), scanned A, a copy of balatro, Apache-2.0.

An animated background made with WebGL, a browser technology for drawing graphics with the computer's graphics processor. It creates a grainy gradient visual behind hero content and becomes static when reduced motion is preferred.

In plain words
What is it for?
Use it as the background of a marketing hero or other single-view feature section, with text layered above it.
Why use it?
It adds a distinctive visual backdrop without an external library while allowing the foreground text to remain the focus. A dark overlay behind the text helps preserve readability.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

grainient scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (grainient.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

81% identical to balatro — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

grainient

A GPU fragment-shader background (dependency-free WebGL).

How to apply

Copy _fx/shaderbg.js + grainient.js; add <div class="grainient" style="position:absolute;inset:0"></div> behind content.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
